    The 2.4 numbers look correct (slightly slower), the 2.6 numbers do not.


    Nothing obviously wrong from the traces however. If you pin the bzip to a
    given processor do you get different results according to which CPU ?

    (see man taskset for info on the commands)

    If you get very different times on the two processors that will be very
    useful information.
